Thats so... Gay?

Just out of curiosity, how many people get offended when they hear, 'That's so gay!'

Or can count how many times you hear it in a day. I don't know if it's just popular with ignorant high school students, or what because I remember one day counting how many times I was up to about 14 in a 7 hour day.

It's in movies also, and even sometimes in forms of fagot and other harsher words as a 'joke'. I personally get offended with both, because associating 'That shirts gay' or 'You lost by one point! That's gay.' Gay = stupid? Huh? Why not just say it's stupid.

Should fagot be more offensive than 'you're so gay.' Where does it end!?
